An expedient access to the first optically pure ruthenium complexes containing C1-symmetric cyclic (alkyl)(amino)carbene ligands is reported. They demonstrate excellent catalytic performances in asymmetric olefin metathesis with high enantioselectivities (up to 92% ee). Preliminary mechanistic insights provided by density functional theory models highlight the origin of the enantioselectivity.

(Chemical Equotion Present) Single (substitution) is better: New chiral ruthenium metathesis (pre)catalysts with a monosubstituted carbon atom in the N-heterocyclic carbene ligand are highly stable in solution, initiate easily, show very high enantioselectivity and excellent E selectivity in asymmetric ring-opening cross-metathesis (see scheme).
